ABSTRACT:
There is a recording apparatus such as a laser beam printer comprising: a host computer as an external unit for inputting data to be recorded and control command to process the recording data; a recorder to record onto a recording medium in accordance with the input data; an error detector to detect errors in the input control commands; a data generator to generate an error code indicative of the occurrence of the error when the error is detected by the error detector; and a controller to control the recorder so as to record the error code onto the recording medium together with the input data. The error code is recorded as an error pattern of a visible image to the end portion of the recording medium such as a cut sheet paper. With the apparatus, the operator can easily know of the occurrence of the error in the input data and the kind and position of the error without interrupting the recording operation. The recording efficiency is improved.
